We have a fixed time for you, O peoples. If ye fail, at the
appointed hour, to turn towards God, He, verily, will lay violent hold on you,
and will cause grievous afflictions to assail you from every direction. How
severe, indeed, is the chastisement with which your Lord will then chastise
you!
- Baha’u’llah (‘Gleanings from the Writings of Baha’u’llah’)
